Monitoring and Prediction

November is usually the month with the heaviest rainfall in Sri Lanka (average up to mm/ month). After the extremely high rainfall two weeks back, the last week had been relatively dry all over Sri Lanka. However, the US NOAA GFS model predicts rainfall in excess of 125 mm for the coming week from 12-18th of November; the forecast is for high rainfall for the following week as well - 19th-25th of November. This NOAA-CFS model has been skillful lately. The rainfall predictions from the Indian Meteorological Department also predict high rainfall in the next three days.
